Rome Rubenowitsch Warschamow

Rom Rubenowitsch Warschanow ( Russian Ром Рубенович Варшамов ; English transcription: Rom Varshamov; born April 9, 1927 in Tbilisi , † August 24, 1999 in Moscow ) was an Armenian-Soviet mathematician who dealt with coding theory.

Warschamow studied in Tbilisi with Arnold Walfisz (there he was Georgian master in the 100 meter course for students), as well as in Tomsk . He then conducted research in Moscow at the Steklow Institute for Mathematics with Ivan Matwejewitsch Vinogradow , in particular on number and coding theory, and at the Ministry of Radio Technology (on cryptography ). The Gilbert-Varshamov bound was proved by him in 1957 (and independently by Edgar Gilbert in 1952 ). From 1968 he worked in Yerevan and was the director of the computer center (today Institute of Computer Science and Problems of Automation) of the Academy of Sciences of the Armenian SSR. He was the author of more than 25 scientific articles and a member of the Armenian National Academy of Sciences .
